public class StudentTest {
public static void main(String[] args) {
Student s= new Student();
s.setId(1);
s.setName("hui");
s.setAge(23);
Configuration cfg = new Configuration();
SessionFactory sf = cfg.configure().buildSessionFactory();
Session session = sf.openSession();
session.beginTransaction();
session.save(s);
session.getTransaction().commit();
session.close();
sf.close();
}
